Sysprep – hangs on shutdown

1. Sysprep hangs, even with /forceshutdown. After invoking sysprep, the icons disappear and the blue Windows background remains. I then resort to Ctrl/Alt/Del, I click Task Manager and it then says “Saving Settings” and goes to “Windows is shutting down”, but it hangs here as well. I then power off the Master machine. I then clone, using Ghost, and when the Ghosted machine is booted, Sysprep appears to have worked. I am not comfortable that Sysprep does not run successfully without my intervention. Has anyone seen this ? Info: Windows 2000Pro w/SP1, latest sysprep. Thanks !
